云制造服务综合评价方法研究

作为云制造平台中的关键技术之一,云制造服务的综合评价对于整个云制造资源配置至关重要,在云制造服务综合评价中,服务资源的评价是综合评价的基础。针对云制造服务评价问题,根据云制造服务评价体系中评价指标的多样性与云制造服务特点相匹配,基于模糊理论中的模糊数学,建立了模糊综合评价模型,并确定了由层次分析法和熵权法组合确定权重的方法。再根据云制造环境下评价指标的构建原则,选取了七个一级指标和十六个二级评价指标,以上述指标构建了多层次云制造服务评价因素集和对象评语集,从而建立了云制造服务资源综合评价指标体系。最后,通过云制造服务实例验证了该云制造服务综合评价模型及模糊综合评价算法的操作简便性及实用性。

Research on Comprehensive Evaluation Method of Cloud Manufacturing Service

As one of the key technologies in the cloud manufacturing platform,comprehensive evaluation of cloud manufacturing services is crucial to the overall cloud manufacturing resource allocation.In the comprehensive evaluation of cloud manufacturing services,the evaluation of service resources is the basis of comprehensive evaluation.For the evaluation of cloud manufacturing services,according to the diversity of the evaluation indicators in the cloud manufacturing service evaluation system and the characteristics of cloud manufacturing services,based on fuzzy mathematics in fuzzy theory,a fuzzy comprehensive evaluation model is established and the method of weight determination by the combination of analytic hierarchy process and entropy weight is determined.According to the construction principles of evaluation indicators in the cloud manufacturing environment,seven first-level indicators and sixteen second-level evaluation indicators are selected to construct a multi-level cloud manufacturing service evaluation factor set and object comment set,thereby establishing a cloud comprehensive evaluation index system of manufacturing service resources.Finally,the cloud manufacturing service comprehensive evaluation model and the fuzzy comprehensive evaluation algorithm are proved to be simple and practical in operation through an example of cloud manufacturing service.
